What are the geographical frosts in Qinghai?

The precipitation process in Qinghai will continue to need frost prevention.

Affected by the cold air in the north, precipitation occurred again in most areas of Qinghai on the night of September 9, and heavy rain to moderate rain occurred in some areas. The precipitation center appeared in jiuzhi county, Guoluo Prefecture, with a 24-hour precipitation of 37.3 mm, reaching the level of heavy rain, and the precipitation in banma county was 26.7 mm, also reaching the level of heavy rain; The precipitation in Zeku and Jianzha in Huangnan Prefecture exceeded 10 mm, reaching the moderate rain level. This is the fifth consecutive day that Qinghai has experienced a large-scale precipitation weather process.

This long-term continuous precipitation has kept the temperature in Qinghai in a relatively low state. Take the temperature in Xining, the provincial capital, for example. Before the precipitation process, the highest temperature in Xining reached 26 degrees during the day on September 6, and the temperature in Xining plummeted on September 7, and the highest temperature was only 16 degrees. From September 8 to 9, the temperature in Xining remained at a low level. The temperature drop is more obvious in some places with higher altitude in our province. According to meteorologists, after the precipitation ended and the weather cleared, the radiation cooling was very obvious. Therefore, frost weather may occur in Haibei, Xining, Haidong, around the lake and east of Haixi in the later period, especially in the morning of 13 and 14, and prevention should be strengthened.
